A comparative study of clinical end-user and librarian searches. J Clin Epidemiol. Complexity The provision of the functionality we expect of a good DBMS makes the DBMS an extremely complex piece of software. It is likely that topical differences in systematic reviews may impact whether databases such as Web of Science and Google Scholar add value to the review. Lemeshow AR, Blum RE, Berlin JA, Stoto MA, Colditz GA. Searching one or two databases was insufficient for meta-analysis of observational studies. 2005 Jan 8;5:2. doi: 10.1186/1471-2288-5-2. For four out of five systematic reviews that limited to randomized controlled trials (RCTs) only, the traditional combination retrieved 100% of all included references. Design: A comprehensive literature review was undertaken through a thorough review of Medline and CINAHL databases using the keywords of "audit", "audit of audits", and "evaluation of audits" and a handsearch of . The researchers that requested the search received a deduplicated EndNote file from which they selected the references relevant for inclusion in their systematic review. California Privacy Statement, Careers. J Clin Epidemiol. Many of the reviews were initiated by members of the departments of surgery and epidemiology. This implies that 17% of the reviews in the PubMed sample would have achieved an acceptable recall of 95%. The X-axis represents the percentage of reviews for which a specific combination of databases, as shown on the y-axis, reached a certain recall (represented with bar colors). Since May 2013, the first author prospectively recorded results from systematic review searches that he performed at his institution. 3099067 Based on the record numbers of the search results in EndNote, we determined from which database these references came. J Med Libr Assoc. Of all reviews in which we searched CINAHL and PsycINFO, respectively, for 6 and 9% of the reviews, unique references were found. Lorenzetti DL, Topfer L-A, Dennett L, Clement F. Value of databases other than MEDLINE for rapid health technology assessments. From the published journal article, we extracted the list of final included references. One hundred and fifty-nine journals are uniquely indexed in BNI compared with the basic version of CINAHL. It is laborious for searchers to translate a search strategy into multiple interfaces and search syntaxes, as field codes and proximity operators differ between interfaces. Films Media Group serves the education community through its four brands: Films for the Humanities and Sciences, Cambridge Educational, Meridian Education, and Shopware.

An overview of the broad topical categories covered in these reviews is given in Table2. The purpose of this research was to determine which of three databases, CINAHL, EMBASE or MEDLINE, should be accessed when researching nursing topics. Moreover, in combinations where the number of results was greatly reduced, the recall of included references was lower. It therefore finds articles in which the topic of research is not mentioned in title, abstract, or thesaurus terms, but where the concepts are only discussed in the full text. In general, searches are developed in MEDLINE in Ovid (Ovid MEDLINE In-Process & Other Non-Indexed Citations, Ovid MEDLINE Daily and Ovid MEDLINE, from 1946); Embase.com (searching both Embase and MEDLINE records, with full coverage including Embase Classic); the Cochrane Central Register of Controlled Trials (CENTRAL) via the Wiley Interface; Web of Science Core Collection (hereafter called Web of Science); PubMed restricting to records in the subset as supplied by publisher to find references that not yet indexed in MEDLINE (using the syntax publisher [sb]); and Google Scholar. Using the prospectively recorded results and the studies included in the publications, we calculated recall, precision, and number needed to read for single databases and databases in combination. We determined the databases that contributed most to the reviews by the number of unique references retrieved by each database used in the reviews. This database also offers indexing and abstracts for more than 10,100 journals and a total of 10,600 publications including monographs, reports, conference proceedings, etc. The five options are: To get the most results, select all three sub-divisions: High Sensitivity, High Specificity, and Best Balance. 2023 BioMed Central Ltd unless otherwise stated.

MEDLINEprovides authoritative medical information on medicine, nursing, dentistry, veterinary medicine, the health care system, pre-clinical sciences, and much more. Performance was measured using recall, precision, and number needed to read. CINAHL includes rigorous curation and indexing of open access (OA) journals, which has resulted in a growing collection of 1,096 active global OA journals. The other authors declare no competing interests. The three databases were searched for citations on topics selected by three nurse researchers and the results were compared. It is likely caused by difference in thesaurus terms that were added, but further analysis would be required to determine reasons for not finding the MEDLINE records in Embase.

For the databases that retrieved the most unique included references, we calculated the number of references retrieved (after deduplication) and the number of included references that had been retrieved by all possible combinations of these databases, in total and per review. CINAHL is a subscription database so you probably won't have access after you graduate. (DOCX 19kb). This Spanish language database contains full text for 130 peer-reviewed medical journals in native Spanish. <> 'VI/:NAf] N1b v4Fl8KTs cinQ Of those, 15 could not be included in this research, since they had not searched all databases we investigated here. We assessed the frequency at which databases and combinations would achieve varying levels of recall (i.e., 95%). Based on the number of results per database both before and after deduplication as recorded at the time of searching, we calculated the ratio between the total number of results and the number of results for each database and combination. Beyer FR, Wright K. Can we prioritise which databases to search? Subject-specific databases such as CINAHL, PsycINFO, and SportDiscus only retrieved additional included references when the topic of the review was directly related to their special content, respectively nursing, psychiatry, and sports medicine. Syst Rev. Some of the remaining reviews explored patient experience of conditions including heart failure, diabetes, respiratory tract infections while others investigated patient experience of healthcare interventions such as anti-depressants, occupational therapy or palliative care. Using both Web of Science and Google Scholar in addition to MEDLINE and Embase increased the overall recall to 98.3%. CAS Quick Answer: What are Boolean operators? These are mostly unique PubMed references, which are not assigned MeSH terms, and are often freely available via PubMed Central. For a sample of 200 recently published systematic reviews, we calculated how many had used enough databases to ensure 95% recall. A multi-disciplinary database, with more than 6,100 full-text periodicals, including more than 5,100 peer-reviewed journals. We find that Embase is critical for acceptable recall in a review and should always be searched for medically oriented systematic reviews. Most of the previous studies did not include these two databases in their research. The databases avail-able include the Cochrane Collaboration, Medline (in various forms such as PubMed), Best Evidence10and Embase.The most widely used and most often recom-mended database isMedline. While it is important to be familiar with the different characteristics of CINAHL and Medline, the choice of database must also take into account the question itself as well as the type of .

According to our data, PubMeds as supplied by publisher subset retrieved 12 unique included references, and it was the most important addition in terms of relevant references to the four major databases. We are aware that the Cochrane Handbook [7] recommends more than only these databases, but further recommendations focus on regional and specialized databases. Based on these calculations, we estimate that the probability that this random set of reviews retrieved more than 95% of all possible included references was 40%. 11 reviews, where we were able to recheck all the databases used by the original review authors, had included a study that was uniquely identified from the CINAHL database. <> [10] and van Enst et al. 2014;30:1738. endobj Those databases that contributed the most unique included references were then considered candidate databases to determine the most optimal combination of databases in the further analyses. In general, we use the first 200 references as sorted in the relevance ranking of Google Scholar. 2016;5:39. PubMed was used to identify systematic reviews published using our search strategy results. The reviews covered a wide variety of disease, none of which was present in more than 12% of the reviews.
